[求组] 采购订单报表中增加了2个字段 显示库存信息，但是无法读取出来数据 odoo


class purchase_order_line(osv.osv):
    ................

    def _stock1(self, cr, uid, ids, field_name, arg, context=None):
        res = {}
        for order_line in self.browse(cr, uid, ids, context=context):
res[order_line.id] = self.pool.get('stock.history').read_group(cr, uid, [
('product_id', '=', order_line.product_id.id)
], fields=['quantity'], groupby=['location_id'], context=context)

        return res


    _columns = {
        'name': fields.text('Description', required=True),
        'product_id': fields.many2one('product.product', 'Product', domain=[('purchase_ok','=',True)], change_default=True),
........
        'stock1': fields.function(_stock1, method=True, type='float',  string='Stock1', help="This is Stock1"),
        'stock2': fields.function(_amount_line, string='Subtotal', digits_compute= dp.get_precision('Account')),
        }

==================
stock1 这个仓库信息 显示不来数据，程序能编译通过

最终想弄成这样子
    def _stock1(self, cr, uid, ids, field_name, arg, context=None):
        res = {}
        for order_line in self.browse(cr, uid, ids, context=context):
res[order_line.id] = self.pool.get('stock.history').read_group(cr, uid, [
('product_id', '=', order_line.product_id.id),
('location_id', 'ilike', '物理库位 / JG / 库存')
], fields=['quantity'], groupby=['location_id'], context=context)
